METHOD OF LEAK TESTING LARGE VOLUME TANKS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01M3/10 G01M3/38 

FIELD: testing equipment.

SUBSTANCE: device comprises a bell-shaped control head (3) mounted on the corresponding container (1) in the area of its valve (2). The control head (3) forms a test space (4) for the container (1) and a valve (2) therein, accommodating the container in the region of the clutch (1.2), loaded with ambient pressure or vacuum. In the control head (3), there is a chamber (9), which is provided at the rear of the window provided with a glass (10) and which is guided to the container in the region of the valve (2) mounted in the test space (4). A pressure sensor (8) is provided in the control head (3) to record the pressure in the test space (4). For a leak test, a pressure difference is created between the interior of the container (1) and the test space (4) or the corresponding pressure difference is increased by evacuation or vacuum. When the sensor device is not sealed with, at least, one camera (9), the output of the pourable product is recorded in the test space (4) and/or foam formation of the pourable product in the test space (4).

EFFECT: increasing the productivity and reliability of leak tests.
